Closure device for a container
Abstract
A closure device for closing a container opening of a container,
in particular a drinks bottle, has a lid element, a chamber
arranged on the cover element and an inner housing. The chamber and
the inner housing have closers and openers corresponding to one
another, which interact with one another in such a way that a
medium contained in the chamber can move into the container as a
result of a movement of the lid element relative to the inner
housing. In order to create an alternative closure device, which is
particularly simple to produce and can be produced from as few
individual components as possible, the closer is a closure pin
which is securely connected to the chamber, and which can be
removed from a closure opening of the inner housing forming the
opener by a movement of the lid element relative to the inner
housing.

TECHNICAL FIELD
The invention pertains to a closure device for closing a container
opening of a container, particularly a beverage bottle, wherein the
closure device features a lid element, a chamber arranged on the
lid element and an inner housing, and wherein the chamber and the
inner housing feature closing means and opening means that
correspond to one another and interact with one another in such a
way that a medium enclosed in the chamber can escape into the
container due to a motion of the lid element relative to the inner
housing.
PRIOR ART
Closure devices of the aforementioned type are known from the prior
art. They serve for sealing a container and for simultaneously
providing a chamber for the separate storage of liquid or powdery
mediums, for example tea essences or the like, such that these
mediums do not immediately come in contact with and/or are mixed
with the contents of the container, for example water, when the
container is filled, but only at the time, at which the closure
device is removed from the container. This is typically the time,
at which the contents of the container should be consumed.
For example, publication WO 2007/129116 A1 describes a closure
device of the aforementioned type, which upon opening a container
sealed with this closure device releases a supplemental liquid
enclosed in the chamber into the container. The closure device
features a lid element, a chamber and an inner housing. The inner
housing has a discharge opening, into which a plug element
connected to the inner housing engages in a sealed fashion. The lid
element and the inner housing are connected to one another by means
of screw threads, wherein the lid element can be raised relative to
the inner housing from a closed position, in which the plug element
seals the discharge opening of the chamber, into a discharging
position, in which the plug element is at least partially retracted
from the discharge opening, in order to thereby produce a passage
from the chamber into the container. In this way, the medium stored
in the chamber can escape into the container, where it is mixed
with the medium enclosed in the container.
U.S. Pat. No. 7,588,142 B1 discloses a closure device, in which a
closing means in the form of a closure cap is provided and
connected to an inner wall of the chamber. The chamber is realized
in a continuously cylindrical fashion. Furthermore, WO 2008/111731
A1 discloses a closure device, in which a closing means, which is
realized in a pin-like fashion on its free end, is arranged
directly on a chamber ceiling and only extends in the region of the
longitudinal axis of the chamber. With respect to its inner
surface, the chamber is realized in a continuously cylindrical
fashion. We furthermore refer to the prior art according to WO
2010/114309 A2.
SUMMARY OF THE INVENTION
Based on the above-described prior art, the invention aims to
disclose a closure device that has an advantageous design with
respect to the closing means and the chamber.
This objective is initially attained in one aspect of the invention
where the closing means is a closure pin that is arranged on the
chamber and can be removed from a closure opening of the inner
housing forming the opening means due to a motion of the lid
element relative to the inner housing, and the opening means
consist of an opening part that features two circumferential
sealing zones, namely a sealing zone that is formed on an outer
circumferential surface of the opening means and interacts with an
inner surface of the chamber and a sealing zone that is offset
inward relative thereto and interacts with the closure pin, wherein
the sealing zones are furthermore arranged concentric to one
another in a direction extending perpendicular to a moving
direction of the opening means relative to the chamber when the
closure device is opened.
The above-defined objective is furthermore attained in another
aspect of the invention where the closing means is a closure pin, a
sealing element is arranged between a sealing end of the closure
pin and the closure opening, and an additional sealing element is
arranged between an inner surface of a discharge nozzle and an
outer surface of a channel dome of the inner housing such that two
circumferential sealing zones are formed, wherein said sealing
zones are furthermore arranged concentric to one another in a
direction extending perpendicular to a moving direction of the
opening means relative to the chamber when the closure device is
opened.
The closing means, namely the closure pin, is arranged on the
chamber whereas the opening means, i.e. the closure opening, is
formed on the inner housing. In a closed position of the closure
means, the closure pin seals the closure opening in that it either
engages into or covers the closure opening. The closure pin is
removed from the closure opening when the closure device is opened,
i.e. when the lid element is spaced apart from the container--and
the chamber is thereby simultaneously displaced relative to the
inner housing--such that the medium enclosed in the chamber can
flow into the container through the closure opening. During the
production of the closure device, the chamber is advantageously
inserted into the inner housing concentrically, wherein the closure
pin is simultaneously displaced into a position, in which it seals
the closure opening. Since the closure pin preferably is rigidly
connected to the chamber, it also maintains its position and
orientation relative to the chamber during the assembly of the
closure device such that the closure pin automatically comes in
contact with the closure opening due to the position and
orientation on the chamber. The rigid connection is particularly
realized in the form of a rigid connection in the axial
direction.
The opening means may respectively interact with the chamber on the
two concentrically arranged sealing zones. In this context, it is
possible to realize an interaction with a closure pin, which
preferably is rigidly connected to the chamber, as well as an
additional interaction with a receptacle opening for the opening
means on the chamber, which is realized such that it surrounds the
closure pin.
A medium to be discharged from the chamber is preferably under
pressure. If the medium consists of a liquid, a corresponding
compressed gas region may for this purpose be provided above a
liquid level during the filling process.
A secure seal, which can also be inexpensively realized with
respect to the production technology, is particularly important for
such a pressurized medium.
Due to the fact that two concentric sealing zones are formed, two
circumferential regions, preferably cylindrical regions, can be
suitably encompassed in a sealed fashion. This may particularly
concern a cylindrical inner surface and a cylindrical outer surface
of corresponding regions of the chamber, which are encompassed by
the opening means in a sealed fashion.
It is proposed that the closure pin is realized integrally with the
chamber. In this context, it is particularly advantageous to
jointly produce the chamber and the closure pin by means of a
plastic injection molding process such that no separate production
step for connecting the closure pin to the chamber is required. An
injection molding process can be advantageously utilized in this
case because the chamber is usually made of a plastic, for example
polybutylene terephthalate (PBT) or also polypropylene (PP) or
polyethylene (PE). Due to the integral design of the closure pin on
the chamber, its position and orientation relative to the chamber
remain constant such that the closure pin is reliably moved into a
position, in which it seals the closure opening, when the chamber
is connected to the inner housing. As an alternative to this
integral design, however, it would basically also be possible to
arrange the closure pin on the chamber in a different way. For
example, the closure pin may be bonded or welded to the chamber. In
this context, it is important to produce a rigid connection between
the chamber and the closure pin such that the closure pin cannot be
separated from the chamber during the insertion into the closure
device.
It is furthermore proposed that the closure pin has a freely
projecting sealing end that can be inserted into the closure
opening. For example, the closure pin may be arranged on the
chamber wall like an L-shaped web such that the free sealing end
points in the direction of the closure opening of the inner
housing. If the chamber is realized cylindrically, the end region
of the closure pin carrying the sealing end is arranged on the
longitudinal axis of the chamber.
Different designs of the closure pin would basically also be
conceivable. For example, multiple webs arranged in a star-shaped
fashion may also radially extend from the inner wall of the chamber
to the longitudinal axis, wherein the webs carry the end region
with the sealing end in a star-shaped fashion. In this case, the
closure pin is advantageously arranged in a section of the chamber,
which is tapered relative to the remaining chamber like an outlet
region, such that the chamber has a reduced diameter in the region
of the closure pin.
In addition, the sealing end advantageously has a diameter that
essentially corresponds to the inside diameter of the closure
opening. In this case, the outside diameter of the sealing end and
the inside diameter of the closure opening are correspondingly
realized in such a way that the sealing end can be inserted into
the closure opening, if applicable with a sealing element arranged
in between. The sealing end is therefore inserted into the closure
opening like a plug. If the sealing end is alternatively not
inserted into the closure opening, but rather seals the closure
opening from outside, it is advantageous to realize the sealing end
with a correspondingly larger diameter than the closure
opening.
It is proposed to assign a sealing element to the closure opening
and/or the closure pin in order to produce a fluid-tight seal
between the closure opening and the closure pin. A sealing element
for producing a fluid-tight connection between the sealing end and
the closure opening is advantageous in instances, in which the
sealing end of the closure pin is arranged in front of the closure
opening, as well as in instances, in which the sealing end projects
into the closure opening. The sealing element may advantageously
consist of a rubber seal or the like. This sealing element may
either be arranged on an edge region of the inner housing that
defines the closure opening, on the sealing end of the closure pin
or on the closure opening and on the closure pin.
A sealing element is advantageously assigned to the inner wall of
the closure opening, wherein the inner wall is particularly coated
with the sealing material. In this context, it is proposed to
insert the sealing end of the closure pin into the closure opening
such that the sealing element/the coating is arranged in between.
Due to the interior coating of the closure opening with a sealing
material, it is possible to realize a sealing element that always
maintains its position on the closure opening and thereby
contributes to optimally sealing the closure opening.
It is furthermore proposed that the closure opening forms part of a
flow channel, the length of which corresponds to at least five
times its diameter and to no more than twenty times its diameter.
The medium being discharged from the chamber therefore has to flow
through the flow channel in order to reach the container. In this
way, the medium is not discharged from the chamber in a surge-like
fashion, but rather in the form of a relatively fine jet over a
certain period of time. This ultimately also promotes the superior
miscibility of the medium enclosed in the container and the medium
being discharged from the chamber. In this case, the sealing end of
the closure pin does not have to be inserted into the flow channel
over the entire length thereof, but rather may only be inserted
into the flow channel in the region of the closure opening, for
example, with a section that has a length of a few millimeters. In
this way, the process of joining the chamber with the inner housing
is simplified because the sealing end or the closure pin does not
have to be inserted into the flow channel over a greater length,
particularly not over the entire longitudinal extent of the closure
pin and/or the flow channel.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention is described in greater detail below with reference
to exemplary embodiments. In the drawings:
FIG. 1 shows a section of a container with a closure device
arranged thereon,
FIG. 2 shows a lid element of the closure device with a chamber
arranged thereon,
FIG. 3 shows an inner housing of the closure device, and
FIG. 4 shows the closure device in a discharging position.
DESCRIPTION OF THE EMBODIMENTS
A closure device 1 with a chamber 6 that features a lower opening
is illustrated in the figures and described below, wherein opening
means that make it possible to empty the chamber 6 are provided
relative to said lower opening. The opening means particularly
consist of an opening part, which in the exemplary embodiment is
specifically realized in the form of a sealing element 10. This
opening part features two circumferential sealing zones, namely a
sealing zone that is preferably formed on an outer circumferential
surface of the opening means and interacts with an inner surface of
the chamber 6, and an additional sealing zone that is offset inward
relative thereto and in the exemplary embodiment interacts with the
closure pin 7. The aforementioned sealing zones are arranged
concentric to one another in a perpendicular direction--referred to
a moving direction R of the opening means relative to the chamber 6
when the closure device is opened.
FIG. 1 shows an upper section of a container 2, in this case a
beverage bottle, on the container opening 3 of which a closure
device 1 is arranged. The closure device 1 is in a position
relative to the container 2, in which it seals the container
opening 3 in a fluid-tight fashion. The closure device 1 is usually
screwed on the container 2 such that the container opening 3 is
sealed. In this state, the container 2 can be stored for a
prolonged period of time without the contents escaping from the
container 2. In order to open the container 2, the closure device 1
is usually unscrewed from the container 2 such that the container
opening 3 ultimately is completely opened.
The closure device 1 features a lid element 4, a chamber 6 arranged
on the lid element 4 and an inner housing 5. In
the--non-restrictive--embodiment shown, the lid element 4 is a
plastic lid consisting, for example, of polypropylene (PP) or
polyethylene (PE). The chamber 6 is sealed with a foil element 12.
This foil element 12 advantageously is an aluminum foil, but may
also consist of a plastic material such as, for example, EVOH
(ethylene vinyl alcohol copolymer), PET (polyethylene
terephthalate) or the like. If the foil element 12 consists of
aluminum, it is preferably coated with a varnish for the material
of the chamber 6, particularly PBT, on the side that points in the
direction of the chamber 6. A varnish suitable for use in
conjunction with the lid element 4 is advantageously applied on the
opposite side of the foil element 12 that points in the direction
of the lid element 4. The foil element 12 preferably is
respectively welded to the chamber 6 and the lid element 4. The
opening is used for filling the chamber 6 with a medium prior to
sealing the chamber 6 with the lid element 4.
The lid element 4 may also consist, for example, of an aluminum lid
that is rolled onto the container 2 although such an aluminum lid
is not explicitly illustrated in the inventive embodiment. This is
particularly advantageous in conjunction with glass containers.
The chamber 6 is connected to the inner housing 5 by means of
corresponding threads. The inner housing 5 is pressed into the
container 2 in the region of the container opening 3 by means of a
compression seal. The lid element 4 and the container 2 furthermore
feature corresponding threads, by means of which the lid element 4
is connected to the container 2.
The chamber 6 is preferably realized cylindrically and arranged
coaxially within the inner housing 5. The chamber features a
closure pin 7, which is realized integrally with the chamber 6 (for
example by means of a plastic injection molding process), in the
region of its face that points in the direction of the inner
housing 5. The closure pin 7 is designed in an L-shaped fashion and
extends--starting from the inner wall of the chamber 6--to the
longitudinal axis of the chamber 6. The closure pin 7 furthermore
has a freely projecting sealing end 9 that lies on the longitudinal
axis and points in the direction of a closure opening 8 formed on
the inner housing 5.
The closure pin 7 may basically have different shapes. As an
alternative to the single L-shaped web shown, it would also be
possible, for example, to provide a plurality of webs that radially
extend from the chamber axis in the direction of the inner wall of
the chamber 6 and position the sealing end 9 on the chamber axis.
In this case, flow-through openings, through which the medium
enclosed in the chamber 6 can flow out of the chamber 6 in the
direction of the inner housing 5, are formed between adjacent
webs.
The sealing end 9 of the closure pin 7 can be inserted into the
closure opening 8 of the inner housing 5. In this case, the closure
opening 8 forms part of a flow channel 11 that is oriented parallel
to the longitudinal axis of the closure device 1, as well as to the
longitudinal axes of the chamber 6 and the inner housing 5. The
flow channel 11 has a length that approximately corresponds to ten
times its diameter. The flow channel 11 is arranged within a
channel dome 14 formed on a face of the cylindrical inner housing
5, wherein the material thickness of the inner housing 5 is in this
region widened in a dome-like fashion in order to define the flow
channel 11. The diameter of the closure opening 8 and the flow
channel 11 essentially corresponds to the diameter of the sealing
end 9 such that the sealing end 9 can be respectively inserted into
the closure opening 8 or the flow channel 11 in a sealed fashion.
In the exemplary embodiment shown, a sealing element 10 is
respectively arranged between the sealing end 9 of the closure pin
7 and the closure opening 8 or the flow channel 11 in order to
produce a fluid-tight connection. In the closed state of the
closure device 1 shown, the sealing end 9 respectively engages into
the closure opening 8 or the flow channel 11 with the sealing
element 10 arranged in between such that the medium enclosed in the
chamber 6 can no longer flow into the container 2 through the flow
channel 11. In this case, the sealing element 10 is realized in the
form of a rubber seal, but it would alternatively also be possible,
for example, to respectively coat the inside of the closure opening
8 or the flow channel 11 with a sealing material.
In the closed state of the closure device 1 shown, the channel dome
14 protrudes into a discharge nozzle 13 of the chamber 6 over a
certain axial length such that the sealing end 9 of the closure pin
7 is respectively engaged with the closure opening 8 or the flow
channel 11.
FIG. 2 shows the chamber 6 in a pre-assembled state on the lid
element 4. In this state, the chamber 6 is already sealed with the
foil element 2. The discharge nozzle 13 carrying the closure pin 7
is formed on the face of the chamber 6 that points away from the
lid element 4. In this case, the closure pin 7 radially extends
from the inner wall of the discharge nozzle 13 to the longitudinal
axis of the chamber 6 and from there in the direction of its
sealing end 9 parallel to the longitudinal axis.
FIG. 3 shows the inner housing 5 of the closure device 1 in a state
prior to being joined with the lid element 4 and the chamber 6. The
channel dome 14, which respectively features the closure opening 8
or the flow channel 11, is formed on the lower face of the inner
housing 5. On the inside of the inner housing 5, the channel dome
14 is covered by the sealing element 10 that at least partially
protrudes into the closure opening 8 or the flow channel 11,
respectively. In this case, the sealing element 10 consists of a
rubber seal that is realized separately of the inner housing 5 and
inserted into the inner housing 5 such that it covers the channel
dome 14 and at least partially protrudes into the flow channel 11
prior to connecting the chamber 6 to the inner housing 5.
FIG. 4 shows the closure device 1 with the lid element 4, the
chamber 6 and the inner housing 5, which is concentrically pushed
over the chamber 6 and engages into the lid element 4 with an upper
edge region. This figure shows the open state of the closure device
1, in which the chamber 6 and the inner housing 5 are--in contrast
to the closed position shown in FIG. 1--spaced apart from one
another such that the closure pin 7 is retracted from the closure
opening 8 and the sealing end 9 no longer engages into the flow
channel 11. However, the discharge nozzle 13 of the chamber 6 and
the channel dome 14 of the inner housing 5 are still engaged with
one another in this state such that the medium enclosed in the
chamber 6 can only flow from the chamber 6 into the container 2
through the flow channel 11. The removal of the sealing end 9 from
the closure opening 8 is achieved due to a rotation of the lid
element 4 with the chamber 6 arranged thereon relative to the inner
housing 5, which in turn is realized by unscrewing the closure
device 1 from the container 2.
In the production of the closure device 1 shown, as well as its
arrangement on the container 2, the inner housing 5 is initially
prepared, for example, by inserting the sealing element 10 into the
inner housing 5 such that the channel dome 14 is covered by the
sealing element 10. The chamber 6 is subsequently inserted into the
inner housing 5 until the closure pin 7 protrudes into the closure
opening. The chamber 6 is then filled, sealed with the foil element
12 and connected to the lid element 4. This is the closed position
of the closure device 1, in which the medium enclosed in the
chamber 6 cannot escape. Subsequently, the closure device 1 can be
screwed on the container 2 in order to seal the container opening
3. In this state, the medium enclosed in the container 2 also can
no longer escape from the container 2.
In order to discharge the medium stored in the chamber 6 into the
container 2, it is necessary to move the closure device 1 into a
discharging position. This is achieved by taking hold of the
closure device 1 on the lid element 4 and rotating the closure
device relative to the container 2 in the usual counterclockwise
direction. In this way, the lid element 4 with the chamber 6
arranged thereon is spaced apart from the inner housing 5, which is
clamped in the container opening 3. As the chamber 6 is axially
spaced apart from the inner housing 5, the closure pin 7 is removed
from the closure opening 8 such that the flow channel 11 for the
medium from the chamber 6 into the container 2 is opened. As the
removal of the lid element 4 from the container 2 continues, the
inner housing 5 is ultimately also separated from the container 2
such that the container 2 is now open and the mixed medium can be
withdrawn from the container 2.
